There seems to be something with the event queue. I had the same problem
with the Music dialog freezing with JEDI-QuickTime for Delphi (that doesn't
use the apple activex control, but talks to qt api directly). See the music
demo in the JEDI-QuickTime distro at http://www.delphi-jedi.org, at the
QuickTime section for the freeze.
Wonder if it's related by chance to the FPU flag issues that QT has with
Delphi, see mention at the page of JEDI QuickTime, or some post by John (I
think) on this list sometime ago with way to bypass that. Maybe bypassing it
solves the dialog freeze issue too, maybe not (you may need some extra
thread to work as message pump for that dialog or something).
All QuickTime dialogs seem to have this problem with Delphi
